Answer:
Step-by-step explanation:
There are 3 blue cubes, 8 ref cubes and 4 yellow cubes, which gives a total of 15 cubes.
Now, if you pick 360 times from the bag, the chances to get a blue cube is 100%, because there's only 15 cubes in total. For trial number 16, you wouldn't have any more cubes.
Therefore, after 360 attempts, there's a 100% probability of picking a blue cube.
